Problem #1: Galaxy S6 won’t connect to a Wi-Fi network

My Galaxy S6 used to work with Wi-fi at several restaurants etc. All of sudden, we were at Panera bread and the Wi-Fi gave me a message that the Google settings won’t let you connect, go to connectivity. well I go there and follow quick tip on how to connect but it didn’t work. When I get home all of sudden my phone Wi-fi connects with no problem at all. Take in mind this just started doing this. Thinking something was turned on or off. Also please note, thus phone has no service with a provider. Used with wi-fi only. Thanks for your help. — Toni

Solution: Hi Toni. If the disconnection only happened at one particular restaurant, then the problem may not be on your phone but Wi-fi network in that establishment. Make sure to connect to other Wi-Fis first to see if this problem only occurs with one network or not.

If the same problem happens in at least another Wi-Fi network, make sure to do a factory reset. Here’s how:

  • Turn off your Samsung Galaxy S6 Edge.
  • Press and hold the Volume Up, Home and Power keys together.
  • When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  • Wait until the Android Recovery Screen appears after about 30 seconds.
  • Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  • Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  • After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Problem #2: Galaxy S6 Edge won’t boot normally | Galaxy S6 Edge bootloop issue

To start off my Samsung Galaxy S6 Edge is bone stock, never modified with CFW or rooted nor has it needed any hardware repairs. I woke yesterday morning to find the phone in the off but charging state. Upon powering up the phone it booted to the point of asking me for my password but halfway through typing the phone restarted. The phone continued to act in this way. I tried booting in safe mode, wiping the cache, wiping data/restore default. The phone would boot to the point of optimizing apps get through a random number of apps and restart never completing. I then brought out the Odin gun hoping fresh firmware would be the cure but the phone still boot loops, getting part way through optimizing apps and restarting. I have tried flashing older FW but the phone never gets past the carrier logo. The phone has good battery life and does not crash in the maintenance menus or download mode and I don’t believe hardware to be the problem. I would really appreciate your advice because I am out of ideas. — Keytops

Solution: Hi Keytops. You can only do so much when trying to fix this issue. If you never attempted to modify the official software prior to noticing this problem and the device was never dropped or exposed to elements (heat and water), then an unknown bootloader glitch may have developed. We say you’ve done everything already. Call Samsung and let them replace the phone.

Problem #3: Galaxy S6 stopped responding after switching Ultra Power Saving Mode on

Was listening to music and then went to place the phone into ultra power saving mode. I set the phone down and then all of a sudden the screen went black and the notification light was on. I pressed every button even tried to reset and the phone would not turn on. I left it alone for a few hours and then tried to place it on the charger but it would not recognize the charger. Even tried to reset it while on the charger but nothing. the screen is still black and the blue notification light is on. I already recieved a replacement phone but was wondering if there was a way to fix this or just retrieve my files from the phone. I happen to be one of those idiots who didn’t back up my phone 🙁 Please help! — Terrie

Solution: Hi Terrie. If the phone has frozen or the system is totally not responding anymore, no, there’s no way to back your files up. The only thing that you can try is to press and hold the “Power” and “Volume Down” buttons for about 10 seconds until the device powers off. Doing so will force the phone to restart. If it remains stuck, drain the battery and charge it again before attempting to start it again. If still nothing, you’re out of luck.

Problem #4: Galaxy S6 won’t fast charge when it is ON

i purchased my device 8 months back. it was charging fast and was absolutely normal but 2 days back it was charging slowly (screen was turned off). so I turned off my phone to see if its charges fast when device is off. it was charging fast like before and then my device was normal like before. I was charging with only my screen off.

But today again it’s charging slowly (was in screen off) again I turned off my device. it became normal, charging speed was increased. So what should I do now? Why is my device behaving like this? here after I should turn my device off to charging my phone fast?

One more question. When should we turn power saving mode on? if we turn on forever will it damage the device? — Sou

Solution: Hi Sou. If your device appears to charge slowly when it’s powered on, there’s high likelihood that there may be a lot of apps and services running actively and in the background. This means that the phone, even if you shut the screen off, is still using huge amount of battery power. To address the situation, these are things that you can try while charging:

  • Close all active apps.
  • Turn internet connectivity off (mobile data and Wi-Fi) to prevent apps from syncing or downloading and uploading to remote servers.
  • Turn off Master Sync feature.
  • Uninstall apps, especially those that you don’t recognize or don’t use anymore. The lesser the number of apps you have, the smaller the chance of having a bad one.
  • Make sure that your phone is clean of viruses or malware.

If these simple tricks won’t remedy the situation, try to boot your phone in safe mode before charging and observe if there’s a difference. If safe mode is enabled, all third party apps and services will be prevented from running so it’s a good way to know if one of your apps is causing fast battery drain. Here are the steps on how to boot in safe mode:

  • Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  • Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  • Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  • You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

When should we turn power saving mode on? If we turn on forever will it damage the device? In general, power saving mode in Samsung devices is a special mode designed to extend battery power. There are two types of power saving mode: Power saving mode and Ultra power saving mode.

Power saving mode works by reducing the performance of the device’s processor (CPU) and setting screen brightness lower. It does not turn off network connectivity or disable apps so all functionalities should still be available for the user.

On the other hand, Ultra power saving mode uses more drastic solutions to extend battery life by sacrificing functionalities like network connectivity. The moment you turn ultra power saving mode on, Wi-Fi, GPS, and Bluetooth will automatically be disabled. The screen will be converted to old-school black-and-white tone. Also, cellular connectivity will be disabled the moment the phone’s screen is shut off. And like power saving mode, the CPU speed will be lowered.  All these changes should make give you a few more hours to use your Galaxy S6 as a dumb phone that only allows basic services like SMS and voice calls. Switching to power saving mode or ultra power saving mode won’t damage your phone so you can use any of them anytime you need to extend battery power.

Problem #5: Galaxy S6 screen not turning on | Galaxy S6 screen unresponsive

Hi there. My Samsung Galaxy S6’s screen became unresponsive today and after leaving it for a bit, the screen has gone black. I have tried to restart it but have had no success. I know that the phone still works as I receive notifications and the phone buzzes when I get a message. The screen did flicker when it was unresponsive, and occasionally it flickers from a black screen to a deep blue screen (so it seems like that back light is still working). The back button only occasionally works as well. I’ve read some of the suggestions to hold down the bottom volume button, the home button and the power button but the screen remained black. I haven’t dropped the phone nor has it been dropped in water. The phone is still under its one year warrantee so would this fault be covered by it? Thanks in advance for your help. — Jessica

Solution: Hi Jessica. As mentioned above, try to do a soft reset first (pressing and holding Power and Volume Down for 10 seconds) to see if it works. You can also try to see if you can make the device respond by booting it safe mode.

If that won’t work either, try to see if you can restart it in Odin or download mode. In this mode, you can try to flash or manually install a stock firmware to make the device boot back normally. Here’s how it’s done:

  • Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • Wait until the download mode screen appears.

If the phone remains in the same state, consider having it replaced. As far as Galaxy S6 warranty goes, Samsung follows a simple principle — as long as there’s no sign of hardware and software tampering, the device should still be replaced.

Problem #6: Galaxy S6 unable to connect to company Wi-Fi

This isn’t so much a problem with my phone but it’s more that I made a mistake and am not sure how to fix it.

So my workplace wi-fi is a secure network, but it appears in my wi-fi menu as unsecured. No problem here. I select the network and connect to it, and upon connecting it will open a Web page where I am prompted to input the password to access the Internet through the network. It’s very similar to when you are required to accept the terms of service to access the wi-fi networks of many restaurants. In the top right corner of this Web page is a button that brings up a menu. I’m not sure what possessed me to do this, but one day while connecting to the wi-fi at my workplace, I opened that menu and selected the option called ‘keep connection’. Now I am unable to access the Web page to input my password, and therefore unable to access the Internet through the network. I have tried forgetting the network and reconnecting, as well as attempting to input the Web page URL manually. Also, I tried restarting my phone after forgetting the network. Nothing has worked thus far. I don’t know how to fix this and have been unsuccessful finding help elsewhere online. Any assistance would be much appreciated. — Jamison

Solution: Hi Jamison. You must talk to your company’s IT department to reconnect. We don’t know how your company’s Wi-Fi network is setup so there’s really nothing much that we can tell you to do. There are many ways to configure a Wi-Fi network and we can’t even picture out the menu you’re talking about here.
